In a small bowl, stir the melted butter and sugar together until smooth.
Stir in the egg yolk and vanilla until combined.
In a separate bowl, whisk together the flour, cinnamon, baking powder, and salt.
Add the dry ingredients to the butter mixture and stir just until combined.
Stir in the milk.
Gently fold in the blueberries until evenly distributed.
Spoon the batter into the greased ramekin and smooth the top.
Bake for 30 to 35 minutes, until the top is golden and a knife inserted in the center comes out clean.
For the optional glaze, whisk the powdered sugar, milk or cream, and vanilla in a small bowl until smooth.
Drizzle the glaze over the cake once it has cooled slightly.
Notes
Use a 10-ounce ramekin: This cake is built for a 10-ounce ramekin, about 4 inches wide. The size gives it the right height and matches the bake time below. A larger dish bakes faster, a smaller one slower.Level your flour: With only 5 tablespoons of flour, a heaped or packed spoon throws the ratio off more than it would in a full-size cake. Spoon the flour loosely into the tablespoon and sweep the top level with a knife so the cake doesn't bake up dry or heavy.Don't overmix the batter: Stir the wet and dry together just until the flour disappears. Overmixing builds gluten and makes the cake tough, so a few lumps are fine.Check it at 30 minutes: Ovens vary, so start checking at the 30-minute mark. It's done when the top is golden and a knife in the center comes out clean.If doubling the recipe, bake in two 10-ounce ramekins or one 5x5 inch baking dish.
